Ethereum’s Sepolia test network activated the Glamsterdam upgrade on October 6 and moved to a block gas limit near 200 million. Mainnet remains at a 60 million gas limit, and no confirmed deployment date has been set for that network.

What this rests on

Claim by claim, with its source
✓
Ethereum’s Sepolia test network activated Glamsterdam on October 6.
✓
After the upgrade, Sepolia’s block gas limit rose to nearly 200 million gas, more than three times mainnet’s 60 million limit.
✓
Ethereum mainnet is still at a 60 million gas limit.
✓
No confirmed deployment date has been set for Glamsterdam on Ethereum mainnet.

What it means

Who it affects, what changes and what is still unconfirmed

Each sentence links inside to the piece that supports it.

Users and developers working around Sepolia will notice the higher block gas limit immediately, because the test network is now running with much more room per block than before. That makes the test environment look different today from Ethereum mainnet, which still has a 60 million gas limit.

In practice, Sepolia can now process blocks under the new Glamsterdam setting, while mainnet stays on its earlier limit. What changes is the test network configuration; what does not change yet is the mainnet setting, which remains at 60 million gas.

The move was larger before the first headline than after. That is an observation, not an explanation: the market also moves on things nobody publishes.

How the story was built

Every piece in order, with the time its news medium declares — if it is not believable we use ours and say so — and what it added to what was already known at that point. Arriving first is not the same as adding something.
